1、建立账号
[root@opsedu ~]# groupadd mysql
[root@opsedu ~]# useradd -s /sbin/nologin -g mysql -Mmysql
useradd参数说明:
-s/sbin/nologin 表示禁止该用户登录
-gmysql 指定属于mysql组
-M表示不创建用户家目录
2、配置安装环境
创建目录并授权:
[root@opsedu ~]# mkdir /home/tools
[root@opsedu ~]# mkdir -p /usr/local/mysql
[root@opsedu ~]#mkdir -p /data/mysql
[root@opsedu ~]#chown -R mysql.mysql /usr/local/mysql/
[root@opsedu ~]#chown -R mysql:mysql /data/mysql
安装系统软件包:
[root@opsedu ~]# yum install gcc gcc-c++ make cmakencurses-devel bison perl
配置解析:
[root@opsedu ~]# hostname
opsedu
[root@opsedu ~]# vim /etc/hosts
10.47.129.177 opsedu 添加一条
安装cmake:
[root@opsedu ~]# rpm -qa | grep cmake 使用系统自带cmake,编译时,有时候会报错
cmake-2.8.12.2-4.el6.x86_64 版本2.8.12
[root@opsedu ~]# yum remove cmake –y
[root@opsedu ~]# cd /home/tools
[root@opsedu tools]# wget https://cmake.org/files/v2.8/cmake-2.8.12.tar.gz
[root@opsedu tools]# tar -zxf cmake-2.8.12.tar.gz
[root@opsedu tools]# cd cmake-2.8.12
[root@opsedu cmake-2.8.12]# ./configure
[root@opsedu cmake-2.8.12]# gmake
[root@opsedu cmake-2.8.12]# gmake install
[root@opsedu cmake-2.8.12]# cd ..
[root@opsedu tools]# cmake --version
cmake version 2.8.12
3、安装mysql
[root@opsedu tools]# wget http://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.37.tar.gz
[root@opsedu tools]# tar -zxf mysql-5.5.37.tar.gz
[root@opsedu tools]# cd mysql-5.5.37
[root@opsedu mysql-5.5.37]# cmake \
> -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ \
> -DMYSQL_DATADIR=/data/mysql \
> -DMYSQL_TCP_PORT=3306 \
> -DDEFAULT_CHARSET=utf8 \
> -DDEFAULT_COLLATION=utf8_general_ci \
> -DEXTRA_CHARSETS=all \
> -DENABLED_LOCAL_INFILE=ON \
> -DWITH_INNOBASE_STORAGE_ENGINE=1 \
> -DWITH_FEDERATED_STORAGE_ENGINE=1 \
> -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
> -DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
> -DWITHOUT_PARTITION_STORAGE_ENGINE=1 \
> -DWITH_FAST_MUTEXES=1 \
> -DWITH_ZLIB=bundled \
> -DENABLED_LOCAL_INFILE=1 \
> -DWITH_READLINE=1 \
> -DWITH_EMBEDDED_SERVER=1 \
> -DWITH_DEBUG=0 \
> -DMYSQL_UNIX_ADDR=/tmp/mysql.sock
编译安装:
[root@opsedu mysql-5.5.37]# make
[root@opsedu mysql-5.5.37]# make install
拷贝配置:
[root@opsedu mysql-5.5.37]# ll support-files/*.cnf
-rw-r--r-- 1 root root 4671 Jan 29 15:11 support-files/my-huge.cnf
-rw-r--r-- 1 root root 19759 Jan 29 15:11support-files/my-innodb-heavy-4G.cnf
-rw-r--r-- 1 root root 4645 Jan 29 15:11 support-files/my-large.cnf
-rw-r--r-- 1 root root 4656 Jan 29 15:11 support-files/my-medium.cnf
-rw-r--r-- 1 root root 2820 Jan 29 15:11 support-files/my-small.cnf
[root@opsedu mysql-5.5.37]# /bin/cpsupport-files/my-huge.cnf /etc/my.cnf
创建mysql数据库文件:
[root@opsedu mysql-5.5.37]#/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql--datadir=/data/mysql --user=mysql
启动mysql:
[root@opsedu mysql-5.5.37]# /usr/local/mysql/bin/mysqld_safe --user=mysql&
[root@opsedu mysql-5.5.37]# netstat -lnt|grep 3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
配置mysql:
[root@opsedu ~]# echo ‘exportPATH=/usr/local/mysql/bin:$PATH‘ >>/etc/profile
[root@opsedu ~]# source /etc/profile
配置mysql开机启动:
[root@opsedu mysql-5.5.37]# cpsupport-files/mysql.server /etc/init.d/mysqld
[root@opsedu mysql-5.5.37]# chmod 700 /etc/init.d/mysqld
[root@opsedu ~]# chkconfig --add mysqld
[root@opsedu ~]# chkconfig mysqld on
为mysql root用户增加密码:
[root@opsedu ~]# mysqladmin -uroot password‘q.123456‘
安装之后的选项:
[root@opsedu ~]# mysql -uroot -pq.123456
mysql> select user,host,password from mysql.user;
+------+-----------+-------------------------------------------+
| user | host | password |
